CONTROLS CONTINUED
FIELD CONTROLLABLE FUNCTIONS
HOME SELECTION
If the switch is in the HOME position the heat pump will
operate in its normal mode.
AWAY SELECTION
If the switch is in the AWAY position the heat pump and
thermostat are set to “COOL” mode the heat pump will
operate in accordance to the thermostat setting.
Additionally, the heat pump will cycle on in cooling mode
for 15 minute run times either 4 or 8 times per day
depending on the Dip 1.7 selection. Thermostat still has
priority and will cycle the unit as needed.

If the LED display is flashing “Ay” the thermostat is not set
in cooling mode.
BOILERLESS CONTROL
The system can operate in boilerless mode by switching Dip
1.5. If CO1 goes below the setting of Dip 1.6 the
compressor will be de-energized and control goes into
emergency heat mode staging on “W1”. The compressor
will be locked out for 60 minutes to prevent nuisance
cycling.
The set point for boiler less changeover temperature can
be adjusted by switching Dip 1.6.
WATER-COIL LOW TEMPERATURE CUT-OUT LIMIT
Jumpers JW1-CO1 provide field selection of the
temperature limit settings for CO1.
Not Clipped = 30°F Clipped = 10°F

For all applications below 50°F entering water
temperature, anti-freeze solution is required. Failure to
follow this warning could result in heat exchanger,
equipment or property damage.
ALARM RELAY SETTING
Jumper 3 (JW3 Alarm) provides field selection of alarm
relay terminal AL2 to be jumpered to 24VAC or to be dry.
The alarm relay is activated during lockout mode.
Not Clipped = AL2 Connected to “R”
Clipped = AL2 dry contacts (No connection)
DEHUMIDIFICATION MODE
The system can operate in Dehumidification mode by
switching Dip 1.4 on the WSCM module. In this mode, the
unit will run continuously in fan speed G2 when Y,O, G calls
are given to the board. Dehumidification mode will not run
in heating mode.
WSCM SAFETY FEATURES
ANTI-SHORT CYCLE PROTECTION
The WSCM module incorporates a 5 minute anti-short cycle
protection for the compressor.
RANDOM START
The WSCM module features a 5-80s random start upon
receiving a call to operate.
FAULT RETRY
While in Fault Retry Mode the LED will display a code
representing retry and the fault code. The unit will initiate
the Anti-short cycle timer and try to restart after the delay.
If 3 consecutive faults occur without satisfying the
thermostat the unit will go into hard lockout. The last fault
causing the lockout will be stored in memory and displayed
on the two digit LED display.
WATER-COIL LOW TEMPERATURE CUT-OUT (CO1)
The control module will recognize a CO1 fault during a
compressor run cycle if:
a) Thermistor temperature is below the selected set
point limit.
b) The thermistor temperature is rising at a rate less
than 2°F per 30s time period. The CO1 input is
bypassed for the first 120s of a compressor run
cycle. On the second and third retry CO1 is
bypassed for the initial 90s and 60s of run-time
respectively.
AIR COIL LOW TEMPERATURE CUT-OUT (CO2)
The control module will recognize a CO2 fault during a
compressor run cycle if:
a) Thermistor temperature is below the selected set
point limit.
b) The thermistor temperature is rising at a rate less
than 2°F per 30s time period. The CO2 input is
bypassed for the first 120s of a compressor run
cycle.
